All guests must use virtualized hardware using the x86_64 architecture.
This phrasing is awkward and confusing.
Guest operating systems can be either x86_64 Red Hat Enterprise Linux 6 Beta AP or x86 Red Hat Enterprise Linux 6 Beta AP
I think you're saying it's okay to run 32-bit RHEL on a 64-bit VM, but you cannot run a 32-bit VM. But this is unclear.
All guest operating systems single virtual cluster must be of the same architecture (i.e. either all x86_64 or all x86).
All guest operating systems in a single virtual cluster must be of the same architecture (i.e. either all x86_64 or all x86).
If you are running an x86 guest OS cluster, the following restrictions apply. Either, hosts must use with EPT/NPT hardware, or all x86 guests must have less than 850MB of RAM.
If you are running an x86 guest OS cluster, the following restriction applies: either all virtual guests must emulate EPT/NPT hardware, or all x86 guests must have less than 850MB of RAM.
But that's just a guess as to what you're trying to say...
